I've just checked two chips (so, four CS pins) with new T4 arrived. And it seems to work. So something was definitely wrong in my setup. And thanks for the SCK speed tip. I'll be gradually adding chips to test the whole...

I was fearing SMD for quite some time. It's turned out to be pretty easy with the right tools.
I've got a simple hot air soldering station and an SMD soldering paste. But what makes it really easy — having a stencil...

Hi,
I've made a board under assumption that any digital pin can be used as chip select pin (my board uses 14 digital pins for 14 NOR flash modules). Unfortunately, it doesn't work at all. I've tried setting all 14...

Thanks!
Two things have made me wondering: 5V on pin 8 of 6N138 and the lack of T4 mention on that page.
Makes sense to update that page and add T4 to the table. So that people like me don't increase the entropy...

Hi,
It's probably asked and answered multiple times, but I can't create a search query to find it.
Is the circuit from https://www.pjrc.com/teensy/td_libs_MIDI.html (the first one with 6N138) still the recommended...

After several WTF moments, I've managed to get this chip working.
That chip is actually mentioned here https://github.com/PaulStoffregen/SerialFlash/blob/2b86eb1e43457044ced436a401092076218de2a4/tests.txt#L22 as...

Thanks. I will have that in mind.
I've ordered a couple of S70FL01GSAGMFI013 to try. If I will manage to get them working, I'll order more, otherwise will be trying other approaches.
Theoretically, they seem pretty...

And if I read the datasheet correctly, this chip consists of two parts and requires two chip select pins.
I probably could reduce the number of samples to 500MB, which will require 4 chips and 8 chip select pins...

Why is it always falling down to the insanity... :)
As far as I can find, Cypress S70FL01GSAGMFI013 seems to be the only 1Gb option available to order in Europe.
Not cheap enough to order it blindly though...
There...

I've learned about Mbits some time ago, yeah, it was disappointing.
But given it's SPI, I suppose I would be ok to have an array of, say, up to 4 chips, I can spare 4 pins for the chip select purposes in this...

Hi,
What is the biggest (storage-wise) SPI flash chip known to be properly working with Teensy as of today? Which is available and not obsolete.
I have found a number of Paul's mentions of NAND and that he lacks the...
